    I wasn't planning on using this to make sure the text got to the other MOO
    correctly, I know it will since the network already uses some sort of CRC
    checking.  What I wanted was for BOTH MOOs to generate a CRC of the object's
    code.  If the CRCs match, the MOO will not update anything.  If it doesn't,
    then the host MOO will update the client MOO's code... That way, this group
    of objects will remain exactly the same on both MOOs, incase I decide to
    alter one, I only have to do it once.
